Coronal Hole : Below is a new image courtesy of SDO showing a triangle shaped Coronal Hole currently facing Earth. A Coronal Hole represents a region in the corona that is cooler than its surroundings, and open magnetic field lines are present here. The solar wind flows from Coronal Holes at a high speed and eventually gust past our planet if in a favorable position. The solar wind is expected to increase by September 21 and may lead to minor geomagnetic activity at very high latitudes.

A new sunspot along with plage region 1553 - SDO

Solar Update :Solar activity is currently low with only minor C-Class flares detected within the past 24 hours. A fair sized sunspot rotated into view off the eastern limb on Tuesday morning. Another region rotating into view in the southeast quadrant, is old sunspot 1553. At this time it looks to be a spotless plage. There will remain the possibility of C-Class solar flares and perhaps a small chance for an isolated M-Class event. [Plage - A bright and intensely hot area in the sun's chromosphere, usually associated with a sunspot.]http://www.solarham.net/
